Description

Technical Field

[0001] This utility model relates to the field of constant temperature and humidity equipment technology, specifically a constant temperature and humidity chamber with good sealing performance. Background Technology

[0002] A constant temperature and humidity chamber is an experimental device used to simulate specific environmental conditions. It can accurately simulate humidity and temperature and is commonly used for reliability testing of electronic products, testing of various storage conditions of pharmaceutical products, and testing of food spoilage under different environments. It is also widely used in scientific research in biology, chemistry, and materials, such as cell culture and material performance testing. The doors of existing constant temperature and humidity chambers are all hinged rotating doors. This means that the connection distance between the door and the chamber body is fixed. This means that when fixing the door, pressure can only be applied to the side away from the hinge. After long-term use, problems such as hinge deformation can easily affect the sealing performance between the chamber body and the door. Utility Model Content

[0008] Preferably, the rotating component includes a first bevel gear, which is mounted on the hinge shaft between the support frame and the slide. A second bevel gear meshes with the first bevel gear, and a second motor is mounted below the second bevel gear, which is located under the slide.

[0009] Preferably, the driving component includes a fixing plate located on the back of the work box. A first motor is mounted on the fixing plate, and a drive sprocket is mounted on the output end of the first motor. A chain is mounted on the drive sprocket, and driven sprockets are connected to both ends of the chain. The driven sprockets are connected to a lead screw.

[0010] Preferably, a tensioning component is provided on the back of the work box corresponding to the position of the chain, and the tensioning component is used to tighten the chain.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a constant temperature and humidity chamber with good sealing performance, which has the following beneficial effects:

[0016] 1. By setting up translation and rotation components, when the work box needs to be closed, the rotation component drives the door to rotate to the position facing the opening on the front of the work box through the support frame and the fixed frame. Then, the translation component pulls the door backward through the support frame and the fixed frame, so that the door is tightly pressed against the sealing platform after being subjected to force. This achieves the purpose of applying pressure to both sides of the door at the same time, so that the door fits tightly against the work box as a whole. Moreover, the fitting force can be adjusted and controlled, giving the work box a high sealing performance. This avoids the problem of traditional hinge connections, where the door and the work box are fixed at the hinge position and cannot be sealed by force.

[0017] In addition, when it is necessary to open the box door, the translation component moves the box door out of the working box by fitting it against the support frame and the fixed frame. Then, the rotation component drives the box door to rotate upward through the support frame and the fixed frame, opening the box door. This achieves the purpose of stable and full opening and closing of the box door. Furthermore, the opened box door is placed on the top of the working box, avoiding the occupation of the side space of the working box and greatly reducing the space occupied by the device.

[0018] 2. By setting up airbags and pressure strips, when the translation component pulls the door backward through the support frame and the working box, the pressure strip on the inside of the door will first contact the sealing platform and retract into the door under pressure. After the pressure strip retracts into the door, it will squeeze the airbag, causing the airbag to expand to the side. The expanded airbag will fill the gap between the door and the inside of the working box, further improving the sealing effect between the working box and the door. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4A well-sealed constant temperature and humidity chamber includes a main unit 1, a heat dissipation vent 2 on the side of the main unit 1, a control panel 3 on the front, a working box 4 on the main unit 1, an open front of the working box 4, translation components 7 on both sides of the working box 4, a support frame 12 and a rotating component 8 on the translation components 7, the rotating component 8 is used to drive the support frame 12 to rotate, a drive component 6 connected to the translation components 7 on the back of the working box 4, a fixed frame 13 at the front end of the support frame 12, a door 5 on the fixed frame 13, and a sealing platform 11 that fits against the front of the door 5.

[0027] In this utility model, a translation component 7 and a rotation component 8 are provided. When it is necessary to close the working box 4, the rotation component 8 drives the box door 5 to rotate to the position corresponding to the front opening of the working box 4 through the support frame 12 and the fixed frame 13. Then, the translation component 7 pulls the box door 5 backward through the support frame 12 and the fixed frame 13, so that the box door 5 is tightly attached to the sealing platform 11 after being subjected to force, thereby achieving the purpose of applying pressure to both sides of the box door 5 at the same time, so that the box door 5 is attached to the working box 4 as a whole. Moreover, the force of attachment can be adjusted and controlled, so that the working box 4 has a high sealing performance, avoiding the problem of traditional hinge connection where the box door 5 and the working box 4 are fixed at the hinge position and cannot be sealed by force.

[0028] In addition, when it is necessary to open the box door 5, the translation component 7 moves the box door 5 out of the working box 4 by fitting it against the support frame 12 and the fixed frame 13. Then, the rotation component 8 drives the box door 5 to rotate upward through the support frame 12 and the fixed frame 13, opening the box door 5. This achieves the purpose of stable and full opening and closing of the box door 5. Furthermore, the opened box door 5 is placed on the top of the working box 4, avoiding the occupation of the side space of the working box 4 and greatly reducing the space occupied by the device.

[0029] The translation component 7 includes a slide rail 701, which is located on the side of the work box 4. A lead screw 703 is provided inside the slide rail 701. One end of the lead screw 703 is connected to the drive component 6 for transmission. A slide seat 702 is provided inside the slide rail 701 that is threadedly engaged with the lead screw 703. The slide seat 702 is rotatably connected to the support frame 12.

[0030] By setting the slide rail 701 and the lead screw 703, the lead screw 703 can drive the slide block 702 to move linearly by its own rotation, so that the slide block 702 can drive the support frame 12 and the fixed frame 13 to move horizontally, and use the fixed frame 13 to drive the box door 5 to move horizontally, so as to open or close the box door 5 and the working box 4, and make the pressure on both sides of the box door 5 consistent. The slide rail 701 can regulate and restrict the movement path of the slide block 702, so that the slide block 702 can stably maintain horizontal linear movement.

[0031] The rotating component 8 includes a first bevel gear 801, which is mounted on the hinge shaft between the support frame 12 and the slide 702. A second bevel gear 803 is meshed with the first bevel gear 801. A second motor 802 is mounted under the second bevel gear 803. The second motor 802 is mounted under the slide 702.

[0032] By setting a first bevel gear 801 and a second bevel gear 803, the second bevel gear 803 can rotate stably under the drive of the second motor 802, and drive the first bevel gear 801 meshing with it to rotate using its own rotation. When the first bevel gear 801 rotates, it will drive the support frame 12 connected to it to rotate. The support frame 12 is connected to the box door 5 through the fixed frame 13, so that it drives the box door 5 to rotate, so that after the box door 5 is opened, the box door 5 can be rotated upward and unfolded, so that the box door 5 can be fully opened without occupying the space on the side of the work box 4.

[0033] The drive component 6 includes a fixing plate 601, which is located on the back of the work box 4. A first motor 604 is mounted on the fixing plate 601. A drive sprocket 603 is mounted on the output end of the first motor 604. A chain 602 is mounted on the drive sprocket 603. Driven sprockets 605 are connected to both ends of the chain 602. Driven sprockets 605 are connected to lead screw 703.

[0034] By setting up a chain 602, the driving sprocket 603 and the driven sprocket 605 are connected by the chain 602, so that the lead screws 703 connected to the driven sprockets 605 on both sides can work synchronously, ensuring the consistency of the movement of the slides 702 on both sides, so that the door 5 can open and close smoothly. At the same time, the chain 602 transmission method can avoid slippage, further ensuring the consistency of transmission.

[0035] A tensioning component 9 is provided on the back of the work box 4 at the position corresponding to the chain 602. The tensioning component 9 is used to tighten the chain 602.

[0036] By setting the tensioning component 9, the chain 602 can be tightened, so that the chain 602 is in a stable transmission state. It can also automatically compensate for the length changes of the chain 602 caused by long-term use and thermal expansion and contraction, further ensuring the consistency and synchronization of the transmission to the translation components 7 on both sides, and ensuring the long-term normal operation of the transmission.

[0037] The tensioning component 9 includes a connecting plate 901, which is located on the back of the work box 4. A slide rod 904 is slidably fitted inside the connecting plate 901. A spring 905 connected to the connecting plate 901 is provided on the side of the slide rod 904. A movable plate 902 is provided on the slide rod 904. A tensioning sprocket 903 is hinged to the side of the movable plate 902. The tensioning sprocket 903 is in contact with the chain 602.

[0038] By setting up a slide bar 904 and a spring 905, the spring 905 can apply an upward elastic force to the slide bar 904, so that the slide bar 904 can drive the moving plate 902 to move upward. The moving plate 902 can tighten the chain 602 through the tension sprocket 903 hinged to the side, thereby supporting the chain 602, ensuring the tightness and stable transmission of the chain 602, and automatically adapting to and compensating for changes in the length of the chain 602 by utilizing the support of the spring 905 and the extension and retraction of the slide bar 904.

[0039] An airbag 10 is provided on the edge of the door 5, and a pressure strip 14 is slidably provided on the inner side of the door 5 relative to the sealing platform 11, with the pressure strip 14 corresponding to the airbag 10.

[0040] By setting up the airbag 10 and the pressure strip 14, when the translation component 7 pulls the box door 5 backward through the support frame 12 and the fixing frame 13, the pressure strip 14 on the inside of the box door 5 will first contact the sealing platform 11 and retract into the box door 5 under pressure. After the pressure strip 14 retracts into the box door 5, it will squeeze the airbag 10, causing the airbag 10 to expand to the side. The expanded airbag 10 will fill the gap between the box door 5 and the inside of the working box 4, further improving the sealing effect between the working box 4 and the box door 5.

[0041] The inner side of the door 5 is provided with a spring strip 15, the other end of which is connected to the pressure strip 14, and the spring strip 15 applies an outward pushing force to the pressure strip 14.

[0042] By setting the spring bar 15, the spring bar 15 can apply an outward pushing force to the pressure bar 14. When the door 5 is closed, the pressure bar 14 is compressed and contracts inward, so that the spring bar 15 connected to it will be in a compressed state. When the pressure bar 14 loses its compression, the spring bar 15 will release its own elasticity and push the pressure bar 14 back to its original position, so that the pressure bar 14 loses its compression on the airbag 10, and the airbag 10 contracts and returns to its original position.

[0043] Working principle:

[0044] When the box door 5 needs to be closed, the second motor 802 drives the support frame 12 to rotate downward through the second bevel gear 803 and the first bevel gear 801. The support frame 12 drives the box door 5 to rotate to the position corresponding to the opening of the work box 4 through the fixed frame 13. Then, the first motor 604 drives the chain 602 to move through the drive sprocket 603. The chain 602 drives the lead screw 703 to rotate through the driven sprocket 605. The lead screw 703 drives the slide 702 to move by its own rotation. The slide 702 moves in the slide rail 701 and drives the box door 5 to move through the support frame 12 and the fixed frame 13. The box door 5 moves towards the work box 4 and fits against the sealing table 11.

[0045] When the door 5 and the sealing platform 11 are in contact, the pressure strip 14 will be squeezed and retract into the door 5. When the pressure strip 14 retracts, it will squeeze the airbag 10, causing the airbag 10 to expand and seal the gap between the door 5 and the working box 4.

[0046] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
